Product Overview
Whatman Grade 17 Chromatography Paper is a premium-grade cellulose paper engineered for high-performance chromatographic applications. Its ultra-pure composition ensures minimal interference, making it ideal for precise separations in qualitative analysis. The paper features a uniform texture and controlled thickness, guaranteeing consistent flow rates and reproducible results. With a low ash content of less than 0.06%, it minimizes background noise, enhancing detection sensitivity. The medium flow rate (120 mm/30 min) balances speed and resolution, while its high wet strength prevents tearing during handling. This paper is compatible with a wide range of solvents, including water, alcohols, and organic mixtures, without compromising structural integrity. Its acid-free and lignin-free properties ensure long-term stability, preventing degradation over time. The smooth surface facilitates even sample application, reducing streaking and improving separation efficiency. Available in multiple sizes, it caters to diverse experimental needs, from small-scale tests to large-volume applications. The paper undergoes rigorous quality control to meet international standards, ensuring reliability in critical research and educational settings. Its versatility extends to techniques like paper chromatography, electrophoresis, and blot transfer, making it a staple in analytical laboratories.
FAQs
1. What solvents are compatible with Whatman Grade 17 Chromatography Paper?
This paper is compatible with water, alcohols (methanol, ethanol), acetone, ethyl acetate, and most organic solvents used in chromatography. Avoid strong acids or bases that may degrade cellulose.
2. How does the flow rate of Grade 17 compare to other Whatman grades?
Grade 17 has a medium flow rate (120 mm/30 min), faster than Grade 1 (80 mm/30 min) but slower than Grade 4 (180 mm/30 min), offering a balance between speed and resolution.
3. Can this paper be used for quantitative analysis?
While primarily designed for qualitative work, it can support semi-quantitative analysis when proper calibration and standardized procedures are followed.
4. What is the maximum temperature this paper can withstand?
The paper remains stable up to 120?C for short durations, but prolonged exposure above 100?C may affect its structural integrity and chromatographic performance.
5. How should unused sheets be stored for long-term use?
Store in a cool, dry environment (15?25?C, 40?60% humidity) in its original packaging, sealed to prevent moisture absorption and contamination from lab vapors.
